H. M. KINSLEY, OF CHICAGO, ILLINOIS.

Letters Patent No. `60,743, dated January l, 1867.

LUNCH-HEATING APPARATUS.

Y TO) ALL WHOM IT MAY CONCERN:

i Be it known that I, H. M. KINSLEY, ofChicago, in the county of Cook,and State of Illinois, have invented a Portable Self-Heating LunchApparatus; and I do hereby declare that the following is aiull and exactdescrip-i ti/'on thereof, reference being had to the accompanyingdrawings, making part of this specification- Figure 1 being a view inperspective of the apparatus in ordinary form.

Figure 2, a central vertical section of the same.

Like letters designate corresponding parts in both of the figures.

The nature of my invention consists in combining with a can, or itsequivalent, for containing meats and other articles offood, `a smallchamber orompartment for containing a small quantity of alcohol,petroleum, 0r. other heat-producing liquid, suilicient to heat the foodin the can; and also, in combining with the can and chamber, a vessel orcup in whichrto burn the alcohol under thev can, the whole beingconstructed pcrmancntlyw together and used as a single article,substantially as hereinafter specified.

My invention is particularly applicable to self-sealing cans forpreserving cooked meats and the like articles of food; and I propose`most generally to apply the chamber or compartment for containing thealcohol or combustible fluid to the bottom of each can, and to add theburning-pan or cup below that as a base on which the whole may rest; butI do not intend to confine myself to any particular form or arrangementof these parts composing my invention.

The accompanying drawings represent a convenient mode of constructingthe apparatus.

-Let A represent the sealing can or vessel of any kind to which myinvention is applicable, a being the seal; ing cover. To the bottom ofthe can, or the centre, a small chamber, B, is soldered, large eioiighto contain a few spoonsfull of the alcohol, which is introduced througha small aperture, 11 then this aperture is hermetically closed, thusretaining the alcohol permanently in the chamber. Abroad base, O, isadded below the chamber, B, and may form the bottom thereof. It projectsthence as far outl as, er farther, than the edges of the can itself, anda very little distance below the same. Its outer-edge terminates in anarrow rim, c, turned up so as to make a shallow cup, but of suicientcapacity to holdthe alcohol as it ilows from the chamber, B. When thecan is opened and its contents areto be heated, the cap which covers thehole b, opening into the chamber B, is punctpred, or the chamber isotherwise opened, so that the' alcohol iows out into the shallow cup, C,and is then set on fire. The combustion of this alcohol producessuiicient heat to warm the contents of the can as muchas desired. Thisdevice or apparatus will be found to be very convenient and desirablewhen canned meats or other articles of the kind are used in camp, i'eld;Woods, on excursions, 'or wherever thc means of otherwise warming arenot readily at hand. The additional expense of the construction and ofthe alcohol is but triling. The two features of the holding-chamber I3and burning-cup C are not necessarily used together, but they are bothpreferably and most desirably thus employed; and the invention is notsolely applicable to cans for sealing up articles of food.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of a chamber B, for containing alcohol, or itsequivalent, with a` preserving can A, substantially as and for thepurpose herein specified.

I also claim the combination of a burning-cup or dish C with a chamberB, for containing/alcohol, or its equivalent, and a preserving canrA,substantially as and for the purpose herein specied.

The above. specification of my portable self-heating lunch apparatussigned by me this 10th day of November, 1866.
